Core Java Training from fundamentals to advanced

Our Java fundamentals training course is aimed at those new to programming or with basic programming experience who wish to learn the principles of application design and object orientation using Java as the implementation language. This course uses the latest stable release of Java and is constantly updated to reflect the current syntax and best practice for java

Besides the basics of the Java language, this course will teach students the concepts of source code versus compiled code, debugging, the build process and packaging process and project organisation. It will empower students to leverage an IDE for increased productivity and how IDEs assist with best practices.

This Java fundamental course provides the knowledge required to attend the Java SE 11 Developer certification training course.

Our Java SE 11 Developer certification training course covers the objectives of Oracles 1Z0-819 Java SE 11 Developer certification.

Since Java stewardship was moved to the Eclipse foundation the pace of innovation and change in the Java platform has accelerated with new versions of Java being released at a steady pace.

The Java SE11 Developer course is based on the latest long term release of Java SE and is designed to ensure certificate holders have a solid understanding of modern Java, its syntax, and constructs.

Java SE 11 Developer Training Course Outline

Working with Java data types

• Use primitives and wrapper classes, including, operators, parentheses, type promotion, and casting
• Handle text using String and StringBuilder classes
• Use local variable type inference, including as lambda parameters

Controlling Program Flow

• Create and use loops, if/else, and switch statements

Java Object-Oriented Approach

• Declare and instantiate Java objects including nested class objects, and explain objects' lifecycles (including creation, dereferencing by reassignment, and garbage collection)
• Define and use fields and methods, including instance, static and overloaded methods
• Initialize objects and their members using instance and static initialiser statements and constructors
• Understand variable scopes, apply encapsulation and make objects immutable
• Create and use subclasses and superclasses, including abstract classes
• Utilize polymorphism and casting to call methods, differentiate object type versus reference type
• Create and use interfaces, identify functional interfaces, and utilize private, static, and default methods
• Create and use enumerations

Exception Handling

• Handle exceptions using try/catch/finally clauses, try-with-resource, and multi-catch statements
• Create and use custom exceptions

Working with Arrays and Collections

• Use generics, including wildcards
• Use a Java array and List, Set, Map and Deque collections, including convenience methods
• Sort collections and arrays using Comparator and Comparable interfaces

Working with Streams and Lambda expressions

• Implement functional interfaces using lambda expressions, including interfaces from the java.util.function package
• Use Java Streams to filter, transform and process data
• Perform decomposition and reduction, including grouping and partitioning on sequential and parallel streams

Java Platform Module System

• Deploy and execute modular applications, including automatic modules
• Declare, use, and expose modules, including the use of services

Concurrency

• Create worker threads using Runnable and Callable, and manage concurrency using an ExecutorService and java.util.concurrent API
• Develop thread-safe code, using different locking mechanisms and java.util.concurrent API

Java I/O API

• Read and write console and file data using I/O Streams
• Implement serialization and deserialization techniques on Java objects
• Handle file system objects using java.nio.file API

Secure Coding in Java SE Application

• Develop code that mitigates security threats such as denial of service, code injection, input validation and ensure data integrity
• Secure resource access including filesystems, manage policies and execute privileged code

Database Applications with JDBC

• Connect to and perform database SQL operations, process query results using JDBC API

Localization

• Implement Localization using Locale, resource bundles, and Java APIs to parse and format messages, dates, and numbers

Annotations

• Create, apply, and process annotations

The Java EE 7 Application developer training course prepares students to write the Oracle certification 1Z0-900. This course will teach attendees about the key Java EE API used to build web applications and middle-tier components for business-critical applications.

Students who attend this course should have attended the Java SE 11 Developer course or feel comfortable with that course's material. It is aimed at candidates who are already familiar with the basics of Java and wish to master the enterprise APIS available in Java EE.
